According to the exemplary embodiments shown in FIGS. 2A-2M, the batterysystem 200 is shown according to various embodiments. As shown in FIG.2A, the battery system 200 includes a base, shown as mount 202; anenergy storage device, shown as battery pack 204, selectively coupled tothe mount 202; and a drive unit, shown as pedal-assist unit 206, coupledto the mount 202. The pedal-assist unit 206 includes the drive motor 110housed within a housing, shown as central housing 48, of the central hub40. Components of the drivetrain 100 (e.g., the crankset 120, thecrankarms 130, etc.) are coupled to the central housing 48. The centralhousing 48 may also house a gearbox, a controller, power electronics,one or more sensors (e.g., torque sensors), and/or other electroniccomponents configured to facilitate the pedal-assist unit 206 inproviding assistance to a user in pedaling the bicycle 10. For example,the pedal-assist unit 206 may be configured to automatically detect atorque input to the crankarms 130 by a user (e.g., via the feet of arider of the bicycle) and control the drive motor 110 to provide anassistive torque having a magnitude determined as a function of theamount of torque input by the user. The battery system 200 is located atthe central hub 40 of the frame 12.

The mount 202 and the battery pack 204 may provide several advantagesover traditional e-bikes. By way of example, the mount 202 may beconfigured to interface with both the battery pack 204 and thepedal-assist unit 206, thereby providing a unified structure thatfacilitates efficient connection between the battery pack 204 and thepedal-assist unit 206, reduces the space occupied by the battery pack204 and the pedal-assist unit 206, and limits the number of connectiondevices, mounting features, etc. required to secure the battery pack 204and the pedal-assist unit 206 to the bicycle 10. By way of anotherexample, the mount 202 may be positioned between and below the down tube30 and the chain stays 50 such that both the battery pack 204 and thepedal-assist unit 206 are positioned in a low and central position onthe bicycle 10. The low, central position of the battery pack 204 andthe pedal-assist unit 206 provides a low center of mass for the bicycle10, which may improve handling (e.g., balancing, stability, steering,etc.) of the bicycle 10. Additionally, when the bicycle 10 is riddenacross bumps, cracks, potholes, etc., the low-central position of thebattery pack 204 and various features of the battery pack 204 and themount 202 may reduce the risk that the battery pack 204 will bedisrupted, disconnected, etc. as a result of jolts, vibrations, etc. ofthe bicycle 10, as described in greater detail herein.

As shown in FIG. 2A, the mount 202 extends from a bottom end 210 of thedown tube 30 to the chain stays 50, where the mount 202 extends from aforward end 212 of the chain stays 50. That is, the mount 202 extendsalong the length of the central hub 40 of the frame 12. The mount 202includes a leading surface 214 aligned with the underside 217 of thedown tube 30. The leading surface 214 is slightly curved to smoothlytransition from an angle aligned with the underside 217 of the down tube30 to an angle approximately perpendicular to a ground surface (e.g.,the road, a trail, etc.) on which the bicycle 10 can be ridden. Theleading surface 14 may, for example, have a pointed, tapered, orotherwise aerodynamically-optimized profile that matches a curvature ofthe down tube 30. As shown in FIG. 2A, the mount 202 includes a trailingsurface 216 approximately aligned with the seat tube 70 and the forwardend 212 of the chain stays 50. As shown in FIG. 2A, the trailing surface216 is substantially straight (i.e., from the side view in FIG. 2A) andapproximately perpendicular to the ground surface. In other embodiments,the leading surface 214 and/or the trailing surface 216 are otherwiseshaped.

As shown in FIG. 2A, the mount 202 includes a top surface 218 thatextends from the down tube 30 to the forward end 212 of the chain stays50, i.e., along the central hub 40 of the frame 12. The top surface 218is shown as substantially straight and approximately parallel to theground surface. The top surface 218 is positioned slightly below theforward end 212 of the chain stays 50. The top surface 218 is configuredto receive the battery pack 204 such that the battery pack 204 ispositioned along the top surface 218 between (i) the chain stays 50 andthe seat tube 70 and (ii) the down tube 30. The top surface 218 mayinclude a pair of substantially-parallel side walls, such that thebattery pack 204 can be received between the side walls when placedalong the top surface 218. In some embodiments, the central hub 40 ofthe frame 12 defines an internal cavity, shown as center recess 44,formed therein with the top surface 218 forming a floor of the centerrecess 44. In such embodiments, the center recess 44 is configured toreceive the battery via the top side of the central hub 40 of the frame12 (e.g., via a center opening 42 defined by the down tube 30 and thecentral hub 40).

As shown in FIG. 2A, the mount 202 includes a lower surface 220. Thelower surface 220 is concave and is configured to receive thepedal-assist unit 206. That is, the lower surface 220 is shaped to matchan external surface of the pedal-assist unit 206 and to allow thepedal-assist unit 206 to be received by the mount 202 with thepedal-assist unit 206 positioned substantially between the leadingsurface 214 and the trailing surface 216. As shown in FIG. 2A, the mount202 includes side surfaces 222 which join the leading surface 214, thetrailing surface 216, the top surface 218, and the lower surface 220.The side surfaces 222 are substantially perpendicular to the groundsurface on which the bicycle 10 travels and substantially parallel tothe direction of movement of the bicycle 10.

In some embodiments, the mount 202 is manufactured as a separate piecefrom the frame 12 (i.e., separate from the down tube 30, the chain stays50, the seat tube 70), then coupled to the frame 12 (e.g., welded to theframe 12, bolted to the frame 12, bonded, etc.). In other embodiments,for example as shown in FIG. 5A, the mount 202 is manufactured as anintegral part of the frame 12 (e.g., in a common mold or cast with thechain stays 50 and down tube 30, etc.). The frame 12 may, therefore, beformed with the central hub 40 of the frame 12 extending continuouslyfrom the down tube 30 to the chain stays 50 and seat tube 70, with themount 202 positioned along and integral with a bottom side of thecentral hub 40 of the frame 112. The center recess 44 (or channel,passageway, etc.) is formed in the frame 12 such that the battery pack204 can be inserted into the center recess 44 and brought into contactwith the mount 202. In such an embodiment, the top surface 218 of themount 202 may form a floor of the center recess 44. In such embodiments,without the mount 202, the down tube 30 and the chain stays 50 would notbe connected at a lower portion of the bicycle 10 and the bicycle 10 maylack the structural integrity needed for effective use of the bicycle10. Accordingly, in such embodiments, the mount 202 may be included toprovide (i) coupling of the battery pack 204 and the pedal-assist unit206 to the bicycle 10 and (ii) structural support to improve stiffnessof the bicycle 10 and provides sufficient support for the weight of thebattery pack 204 and the pedal-assist unit 206.

As shown in FIG. 2A, the battery pack 204 is positioned (i) along thetop surface 218 of the mount 202 and (ii) between the chain stays 50 andthe down tube 30 (i.e., along the central hub 40). The battery pack 204includes a first portion 230 and a second portion 232. According to anexemplary embodiment, the first portion 230 and the second portion 232are contiguous such that the battery pack 204 is formed as a continuousmember. The first portion 230 is angularly offset from the secondportion 232. The first portion 230 is parallel with the chain stays 50and the top surface 218 of the mount 202, while the second portion 232is parallel with the down tube 30. The angular offset of the firstportion 230 relative to the second portion 232 allows the first portion230 to be positioned along the top surface 218 of the mount 202 with thesecond portion 232 extending from the top surface 218 in a directionaligned with the down tube 30 and towards the head tube 20.

As shown FIG. 2A, the center recess 44 is configured to receive thefirst portion 230 and the second portion 232 of the battery pack 204.The down tube 30, the central hub 40, the mount 202, and the batterypack 204 are thereby designed such that the battery pack 204 may appearto be a continuous member of the down tube 30 when installed as shown inFIG. 2A, as opposed to an alternative design where a battery may bepositioned on an external surface of the down tube 30 and may detractfrom the elegance of the frame design. The central hub 40, the mount202, and the battery pack 204 are thereby designed to maximize aninternal space of the frame and to allow the battery pack 204 to bepositioned in a low position on the bicycle 10.

As shown in FIGS. 2B and 2D-2G, the battery pack 204 is configured as afirst battery, shown as first battery pack 250 (i.e., a first embodimentof the battery pack 204). As shown in FIGS. 2C and 2H-2J, the batterypack 204 is configured as a second battery, shown as second battery pack251 (i.e., a second embodiment of the battery pack 204). According to anexemplary embodiment, the second battery pack 251 is configured toaccommodate more battery cells than the first battery pack 250 such thatthe second battery pack 251 can store more energy than the first batterypack 250 while weighing more and consuming more space than the firstbattery pack 250.

As shown in FIGS. 2B and 2D-2G, the first battery pack 250 includes atop shell 252, a bottom shell 254, and a body 256. The top shell 252 andthe bottom shell 254 substantially encloses the body 256. The bottomshell 254 is configured to interface with the mount 202 and the downtube 30 to allow the first battery pack 250 to be removeably coupled tothe bicycle 10. For example, the bottom shell 254 may substantiallymatch a contour of the top surface 218 of the mount 202 and the centerrecess 44 in the central hub 40. The bottom shell 254 may also include aplate 257 extending therefrom and configured to engage a first lockingmechanism, shown as lock 258, integrated into the mount 202 and theframe 12, as described in greater detail herein. In other embodiments,the plate 257 extends from the body 256 and through (e.g., across, outof, etc.) the bottom shell 254.

According to an exemplary embodiment, the body 256 is configured toreceive multiple battery cells. For example, the body 256 of the firstbattery pack 250 may be configured to receive thirty battery cells. Inthe embodiment shown, the cells are oriented to extend laterally acrossthe bicycle 10. The body 256 may include various conductive pathways(e.g., wiring, etc.) to electrically couple the battery cells to anexternal contact 260 positioned on the body 256. The external contact260 extends from the body 256 beyond (e.g., through, across, out of,etc.) the top shell 252 and the bottom shell 254 and provides forcommunication of electrical current into and out of the battery cells ofthe first battery pack 250, thereby facilitating charging anddischarging of the battery cells. As shown in the examples herein, theexternal contact 260 is positioned on the battery pack 204 such that theexternal contact 260 extends towards a rear of the bicycle 10 and abottom of the battery pack 204 coupled to the bicycle 10. In someembodiments, the body 256 also includes a charge port accessible throughthe top shell 252 and configured to connect to a charging cable thatallows the battery cells to be charged without removing the battery pack204 from the bicycle.

As shown in FIGS. 2C and 2H-2J, the second battery pack 251 includes thebottom shell 254 and the body 256 that are substantially the same as thebottom shell 254 and the body 256 of the first battery pack 250.However, the second battery pack 251 does not include the top shell 252.Rather, the second battery pack 251 includes a top shell 262, whichfacilitates providing a larger internal volume within the second batterypack 251 than the top shell 252 provides within the first battery pack250. Accordingly, more battery cells can be fit within the secondbattery pack 251 than within the first battery pack 250, therebyproviding different amounts of electrical energy storage. For example,the second battery pack 251 may be configured to include forty batterycells. Various numbers of battery cells are possible in variousembodiments.

As shown in FIGS. 2C and 2H-2J, the top shell 262 of the second batterypack 251 has a substantially flat upper surface. The upper surface ofthe top shell 252 of the first battery includes a curvature that tracksthe angular profile between the down tube 30 and the chain stays suchthat the upper surface of the top shell 252 of the first battery pack250 is aligned with both the down tube 30 and the chain stays 50. Byusing the space above the body 256 to provide various sizes ofbatteries, the various sizes of battery pack 204 (e.g., having differentnumbers and/or sizes of battery cells) may be interchangeably mounted onthe bicycle 10 in a uniform fashion, facilitating customization based onmaximum power preferences, weight preferences, maximum operational timepreferences, other performance-based preferences, aesthetic preferences,etc.

As shown in FIGS. 2D-2J, the body 256 has the external contact 260 andthe plate 257 extending from the body 256. The plate 257 extends from anopposite end of the body 256 relative to the external contact 260. Theplate 257 and the external contact 260 extend through (e.g., across, outof, etc.) the bottom shell 254 such that the plate 257 and the externalcontact 260 can engage the mount 202. As shown in FIGS. 2D-2J, aprotrusion 270 extends from the battery pack 204 (i.e., the firstbattery pack 250 or the second battery pack 251) proximate the externalcontact 260. The protrusion 270 may be formed by a combination of (i)the bottom shell 254 and (ii) the top shell 252 of the top sell 262. Theprotrusion 270 is configured to engage a receptacle, lip, recess, orother retaining structure of the mount 202 to help secure the batterypack 204 to the mount 202.

As shown in FIGS. 2K-2M, the lock 258 includes a lock cylinder 280connected to a lock bolt 282, and a baseplate 284 coupled to the lockcylinder 280. The lock bolt 282 can selectively slide relative to thebaseplate 284. A plurality of pads (e.g., rubber pads, etc.), shown aspads 286, are positioned between the baseplate 284 and the lock bolt282. The pads 286 are separated from the lock bolt 282 by a spaceconfigured to receive the plate 257, which extends from the battery pack204. The lock cylinder 280 is configured to receive a key, which can beinserted into the lock cylinder 280 and turned to slide the lock bolt282 relative to the baseplate 284 and the lock cylinder 280. The lock258 may be configured such that the lock bolt 282 is substantiallyimmobile unless the key is inserted into the lock cylinder 280.Alternatively, the lock 258 may be electrically activated (e.g., via thebicycle control system 1000, etc.).

The lock bolt 282 is moveable between a locked position and an unlockedposition by translating in a direction perpendicular to an axis of thelock cylinder 280. In the unlocked position, the lock bolt 282 isretracted towards the lock cylinder 280 and away from the pads 286. Whenthe lock bolt 282 is in the unlocked position, the plate 257 can bemoved into or out of contact with the pads 286. Accordingly, when thelock bolt 282 is in the unlocked position, the battery pack 204 can befreely added to or removed from the bicycle 10.

As shown in FIG. 2L, the plate 257 is prevented from moving away fromthe lock 258 by the lock bolt 282 when the lock bolt 282 is in thelocked position and the plate 257 is in contact with the pads 286. Theplate 257 may compress the pads 286 when engaged by the lock bolt 282(with the lock bolt 282 in the locked position), such that a resilient(springing) quality of the pads 286 forces the plate 257 squeezes theplate 257 between the pads 286 and the lock bolt 282. The lock 258 canthereby prevent the battery pack 204 from being removed from the bicycle10, while also providing a secure connection that substantially preventsshaking, vibration, etc. of the battery pack 204 relative to the bicycle10. Deviation of the battery pack 204 is thereby prevented, resistingboth intentional human manipulation and bumps, jolts, etc. experiencedby the bicycle 10 as the bicycle 10 is ridden over uneven surfaces.

As shown in FIGS. 2B, 2C, and 2M, the lock 258 is integrated into themount 202 such that the lock cylinder 280, the lock bolt 282, thebaseplate 284, and the pads 286 are located on or in the mount 202 andthe lock 258 is positioned proximate the down tube 30. A keyhole of thelock cylinder 280 is accessible from a lateral side of the mount 202 andis substantially flush with a side surface 222 of the mount 202. Thebaseplate 284 and the pads 286 are positioned at the top surface 218 ofthe mount 202 with the lock bolt 282 positioned slightly above the pads286. The lock 258 is thereby positioned to engage the battery pack 204when the battery pack 204 is positioned within the center recess 44 ofthe central hub 40 as shown in FIGS. 2A-2C. As shown in FIG. 2M, thebottom shell 254 and the body 256 may be contoured to accommodate aspace occupied by the lock 258. When the battery pack 204 is secured tothe bicycle 10, the lock 258 is internal to the bicycle 10, with onlythe keyhole-end of the lock cylinder 280 exposed and accessible to auser.

According to the exemplary embodiment shown in FIGS. 2K-2M, the lock 258is a mechanical device without electronic components. In otherembodiments, the lock 258 may be electrically power (e.g., via powerfrom the battery pack 204) and may be controlled via electroniccommunications, for example via a button or other interface located onthe bicycle 10, a key fob, and/or via a mobile device communicable withthe lock 258 via wireless communication (e.g., Bluetooth, near-fieldcommunication, radio-frequency identification, etc.). Various suchmodifications are within the scope of the present disclosure.

The battery pack 204, the mount 202, and the pedal-assist unit 206 arethereby securely positioned in a low, central position on the bicycle10, improving handling and stability of the bicycle 10 by lowering thecenter of mass of the bicycle 10. The battery pack 204 can be easilyremoved from the bicycle 10 by an authorized user (i.e., a person with akey to the lock 258), while the lock 258 prevents theft of the batterypack 204. The battery pack 204 may be removed to facilitate charging ofthe battery pack 204 via the external contact 260, to allow a differentbattery pack 204 to be used (e.g., to switch from the first battery pack250 to the second battery pack 251), etc.

Lighting System

As shown in FIGS. 3A-3J, the lighting system 300 includes various lightsources, shown as one or more taillights 302, a headlight 304, and asignature light 306, that are each formed within or otherwise mounted tothe frame 12 of the bicycle 10. Each of the taillights 302, theheadlight 304, and the signature light 306 include lighting elements(e.g., light emitting diodes (LED), organic light emitting diodes(OLED), polymeric light emitting diodes (PLED), incandescent lightbulbs,etc.) that can be selectively activated and controlled to illuminateareas around the bicycle 10 and/or provide indications to surroundingpeople. Electrical power from the battery pack 204 or from secondary,alternative sources can be used to activate lighting elements within thelighting system 300. When activated, the lighting elements canilluminate the area surrounding the bicycle 10 and provide lighting thatcan be used by an operator of the bicycle 10 to navigate the bicycle 10in reduced-light conditions (e.g., dusk, night-time, fog, etc.).Additionally, the lighting elements promote visibility of the bicycle10, and can alert other motorists or pedestrians that the bicycle 10 ispresent on the roadway or pathway and/or of the operator's intentions(e.g., turn, slow down, etc.).

With specific reference to FIGS. 3A-3G, the taillights 302 of thelighting system 300 are shown in further detail. The taillights 302 arepositioned near the rear end of the bicycle 10, and can be configured toemit light in multiple directions, and particularly behind the bicycle10. For example, each of the taillights 302 can project light laterallyand rearwardly away from the frame 12 simultaneously, which improves theoverall visibility of the bicycle 10.

To provide illumination as discussed above, the taillights 302 areintegrally coupled to dropouts of the dropout assemblies 52, show asright dropout 54 and left dropout 56. The right dropout 54 and the leftdropout 56 can be mirror images of one another, and identical taillights302 can be positioned within each of the right dropout 54 and the leftdropout 56. As shown in FIG. 3A, the right dropout 54 and the leftdropout 56 straddle the rear wheel 150 and have a generally continuousbody 308 that is coupled (e.g., welded or molded) to the frame 12 (i.e.,the chain stays 50 and the seat stays 80). A front end 310 of the body308 is mounted to a rearward portion of the chain stays 50 of the frame12, while the rear end 312 of the body 308 supports the taillight 302.In other embodiments, taillights (and/or “brake” lights) may be mountedto or integrated into other structural elements of the bicycle (e.g.,seat, seat post, the seat stays 80, the seat tube 70, etc.).

As shown in FIG. 3A, the rear end 312 of the body 308 includes a tieredstructure having an outer face 314 and a mounting face 316 inwardlyoffset from the outer face 314. The offset between the mounting face 316and the outer face 314 defines a cavity 318 that can receive and supportone of the taillights 302. The mounting face 316 can be defined by arectangular shape, and can be at least partially surrounded by walls 320extending approximately orthogonally (e.g., within 10 degrees) away fromthe mounting face 316 to the outer face 314 to define arectangular-shaped cavity 318. In some examples, the mounting face 316is offset to one side of the outer face 314 so that the walls 320 extendaround and surround three sides of the mounting face 316, but leave oneside of the mounting face open (e.g., the rear end 312 thereof). Asshown in FIGS. 3A-3G, the mounting face 316 is offset toward an outside322 of the body 308, making the cavity 318 is accessible from both therear end 312 and the outside 322 of the right dropout 54 and the leftdropout 56. The mounting face 316 and the outer face 314 can each beapproximately planar surfaces that are spaced apart from one another andextend obliquely relative to one another. For example, the outer face314 can be angularly offset from the mounting face 316 by an angle ofbetween about 5 degrees and about 45 degrees.

The taillight 302 is embedded into and secured within the cavity 318. Asshown in FIGS. 3E and 3F, the taillight 302 includes a frame 324 thatsupports a circuit board 326. The circuit board 326 supports one or morelighting elements, shown as LEDs 328, which are selectively illuminatedusing electrical power provided by the battery pack 204 or analternative power source. A lens 330 extends around the frame 324 toprotect the circuit board and LEDs 328 and distribute light illuminatedfrom the LEDs 328 outward in a more uniform manner. In some embodiments,the lens 330 can be formed of a red polymeric material, likepolycarbonate, and acts as a diffuser to the light sources. The frame324 and the lens 330 can be adhesively coupled to one another, forexample, to form an enclosed taillight 302 module.

The frame 324 and the lens 330 of the taillight 302 together define theouter perimeter of the taillight 302, and are sized to fit securelywithin the cavity 318. In some examples, the frame 324 is formed as achannel having a continuous shape defined by a bottom wall 332, a backwall 334 extending away from (e.g., perpendicular to, etc.) the bottomwall 332, and a top wall 336 extending away from (e.g., perpendicularto, etc.) the back wall 334. The channel is complimentary to the walls320 and the mounting face 316, and can be received entirely within thecavity 318. A boss 338 can extend from the bottom wall 332, and can beused to help couple the frame 324 and taillight 302, more generally, tothe body 308 of the right dropout 54 and the left dropout 56. As shownin FIG. 3C, a threaded hole 340 can be formed through the boss 338 and athrough hole 342 formed through a bottom of the body 308 can be alignedwith the threaded hole 340 so that a fastener can be passed through thethrough hole 342 and threaded into the threaded hole 340 to secure thetaillight 302 within the cavity 318. When assembled into place, the lens330 can extend parallel to and approximately coplanar with the rear end312 of the body 308. In some embodiments, a first portion 344 of thelens 330 extends parallel to the outside 322 of the body 308, a secondportion 346 of the lens 330 extends parallel to the outer face 314, anda third portion 348 of the lens 330 extends parallel to an inside 348 ofthe body 308. When operating, light emitted by the LEDs 328 can bevisible through each of the first portion 344, the second portion 346,and the third portion 348, which correspond to three differentdirections (i.e., right, left, back).

According to an exemplary embodiment, electrical power is supplied fromthe battery pack 204 through the frame 12 and into taillight 302. Asshown in FIGS. 3E and 3G, a wiring passage 350 is formed through thebody 308 of the right dropout 54 and the left dropout 56, extending fromthe front end 310 through to the rear end 312 thereof. The wiringpassage 350 is defined by a through hole 352 that extends from themounting face 316 toward the front end 310 of the body 308. The wiringpassage 350 continues forward, through the body 308, and into anotherthrough hole 354 formed in and through the front end 310 of the body308. The wiring passage 350 can receive and protect one or moreelectrical wires extending away from the circuit board 326 and the LEDs328 through the body 308 and into the frame 12, where the electricalwires can then be coupled to the battery pack 204 using, for example, awiring harness, bus, or other terminal-style connection that iselectrically coupled to the battery system 200.

Operation of the taillights 302 can be controlled using a centralcontroller (e.g., the bicycle controller 1010 shown in FIG. 6 ) or amicroprocessor formed on the circuit board 326. The bicycle controller1010 can be used to adjust the intensity, number of lighting elementsoperating, frequency, pattern, color, or other operational parameters ofLEDs 328 within the taillight 302 that may be varied. In someembodiments, the bicycle controller 1010 can adjust the intensity of thelight emitted from the LEDs 328 based upon feedback received from othercomponents within the bicycle 10. For example, the bicycle controller1010 can issue a command to increase the intensity of light emitted fromthe LEDs 328 when the bicycle controller 1010 receives an indication(e.g., from a sensor) that the front or rear brakes have been actuatedor otherwise engaged. Additionally, an ambient light sensor can becoupled to the bicycle 10 to monitor ambient light surrounding thebicycle 10 and send an indication to activate the taillights 302whenever the amount of ambient light measured by the sensor falls belowa threshold value. In some embodiments, the bicycle controller 1010 isin communication with turn signals positioned on the handlebars 14 ofthe bicycle 10. Upon receiving an input indicating that one of the turnsignals has been actuated, the bicycle controller 1010 issues a commandto modulate (e.g., pulsate, flash, etc.) the LEDs 328 within thetaillight 302 corresponding to the side of the bicycle 10 where the turnsignal was selected to produce a blinking effect. For example, actuatingthe right turn signal could command the taillight 302 positioned withinthe right dropout 54 to strobe while simultaneously keeping thetaillight 302 in the left dropout 56 on the opposite side of the rearwheel 150 at a constant level of illumination or off (if not on). Insome embodiments, the taillights 302 each remain illuminated wheneverthe bicycle 10 is being operated, but may increase in brightness duringbraking processes.

The bicycle controller 1010 can communicate with the taillights 302through wired or wireless communication methods. In some embodiments,control wires are passed through the wiring passage 350 in the body 308to the taillight 302 to communicate commands from the bicycle controller1010 to the taillight 302. Signals produced by the bicycle controller1010 can be passed along the control wires to the circuit board 326 andto the LEDs 328 in order to adjust operational parameters of thetaillight 302. Alternatively, the circuit board 326 can include acommunications unit (e.g., an antenna, a wireless receiver, etc.) thatcan receive wireless signals from the bicycle controller 1010, one ormore sensors, or other suitable inputs that can then be used to operatethe LEDs 328.

In some embodiments, as shown in FIGS. 3H-3J, the bicycle 10 includes afront light, shown as headlight 304, and/or a conspicuity or “daytime”running lamps, shown as signature light 306, to further improve thevisibility of the bicycle 10 and/or the operator's visibility ahead ofthe bicycle 10. As shown in FIGS. 3H-3J, each of the headlight 304 andthe signature light 306 can be integrally formed within the frame 12near a front end of the bicycle 10, so as to direct light forward, inthe direction of travel of the bicycle 10. Each of the headlight 304 andthe signature light 306 can be supplied with electrical power from thebattery pack 204, using wires that extend through a portion of the frame12.

As shown in FIG. 3H, the signature light 306 is positioned within andintegrally coupled with the head tube 20 of the frame 12. The signaturelight 306 is configured to fit across and around an opening 22 formed inthe head tube 20. The opening 22 in the head tube 20 defines a cavity 24that extends into the head tube 20 toward the down tube 30, and has adepth sufficient to receive the modular lighting assembly of thesignature light 306 and associated wiring used to couple the signaturelight 306 to the battery pack 204. Like the taillights 302, thesignature light 306 can include one or more lighting elements (e.g.,LEDs) that are configured to selectively illuminate based uponoperational parameters of the bicycle 10 or based upon inputs receivedfrom the bicycle controller 1010. In some embodiments, the signaturelight 306 is configured to provide a low-level illumination that is usedto help improve the visibility of the bicycle 10, but which is notintended for use to drive in low or reduced-light conditions. Thesignature light 306 can be provided with electrical power and can remainoperational (e.g., illuminated) whenever the bicycle 10 is in use.Alternatively, the signature light 306 can be selectively activated uponthe detection of a low or reduced-light condition, as measured by anambient light sensor and as instructed by the bicycle controller 1010,or in response to operator activation. As shown in FIG. 3H, thesignature light 306 can be covered by a lens 356 provided with asource-identifying shape or pattern. In some embodiments, the lens 356is configured to extend approximately continuously with an outer surfaceof the head tube 20. Alternatively, the lens 356 can protrude outwardbeyond an outer surface of the head tube 20, forming a boss-likestructure on the front of the frame 12. In some embodiments, thesignature light 306 provides a light-up symbol or logo (e.g., amanufacturer's logo, etc.). In some embodiments, the headlight 304replaces the signature light 306 and is received within the cavity 24.

The headlight 304 can be used to provide additional illumination infront of the bicycle so that the bicycle 10 can be operated in low orreduced-light conditions. As shown in FIGS. 3I and 3J, the headlight 304can be formed integrally within the stem 16 of the frame 12. The stem 16generally includes a body 358 having a front section 360 and a backsection 362 and having an LED light 364 formed integrally within thebody 358. In some examples, the LED light 364 is angled downwardly andoutwardly away from the front section 360 of the body 358 to illuminatearea in front of the bicycle 10. The LED light 364 in the headlight 304,like the taillights 302 and the signature light 306, can communicatewith the bicycle controller 1010 to selectively activate based upondetected operational parameters (e.g., ambient light sensor detecting alow light condition), manual input (e.g., a button or switch on thehandlebars 14 or frame 12 of the bicycle 10), a timer, or other suitablecontrol parameters. In some embodiments, the LED light 364 has multipleillumination settings that can correspond to a high beam and a low beamsetting, and can be toggled manually or automatically by buttons,switches, and/or sensors in communication with the bicycle controller1010.

The body 358 defines and surrounds a channel 366. The channel 366 isconfigured to receive the handlebars 14 of the bicycle 10, which extendtransversely through the body 358 of the stem 16. The stem 16 isconfigured to rotate in unison with the handlebars 14, and can bereceived around and mounted to the front fork 60 using another passage368, which extends approximately perpendicular relative to the channel366. Because the stem 16 rotates with the handlebars 14, the LED light364 similarly rotates with the handlebars 14 so that the LED light 364is always directed in the direction of travel of the bicycle 10.

In some embodiments, the body 358 is an assembly of multiple sectionscoupled together. For example, the body 358 can be formed of a rearsection 370, an adapter section 372, and a front section 374. The rearsection 370 can include the passage 368, and can be secured to the frontfork 60 of the frame 12. The adapter section 372 can be selectivelyreceived within the rear section 370 and the front section 374, and canbe used to adjust a length of the body 358.

The locking system 400 may beconfigured to automatically retract the cable into the frame 12 afterthe bicycle 10 is unlocked from the stationary object.

As shown in FIGS. 4A-4E, a first lock (e.g., a lock, a lockingapparatus, a locking device, a securing device, etc.), shown as lock500, of the locking system 400 includes a body member (e.g., bodyportion, a main portion, a receiving portion, a frame portion, ahousing, etc.), shown as body 502, and a removable member (e.g.,removable portion, a lock portion, a cable extension portion, aselectively extendable portion, etc.), shown as insert 504. The insert504 is configured to be removably received within and selectivelyfixedly couple with the body 502. Specifically, the insert 504 isconfigured to be received within a receptacle (e.g., an opening, anaperture, a hole, a recess, an inner volume, a bore, a chamber, etc.) ofthe body 502, shown as cavity 508. The insert 504 can have across-sectional shape or an outer periphery that corresponds to across-sectional shape of the cavity 508 to facilitate the insertion andremoval of the insert 504 in the body 502.

The body 502 includes a sidewall 514 and a flange 516. The flange 516 ispositioned at a first or proximate end 528 of the body 502 andcircumferentially surrounds the cavity 508 into which the insert 504 isinserted. The flange 516 facilitates fixedly and securely coupling thebody 502 with a bicycle frame member, a tubular member, etc. of theframe 12. The flange 516 and the sidewall 514 are integrally formed orotherwise fixedly coupled to define the body 502.

The body 502 also includes a housing member (e.g., a protrusion, a boss,an extrusion, a housing, etc.), shown as protrusion 506. The protrusion506 extends from a second or distal end 530 of the body 502 and includesan inner or internal volume that is configured to receive and store aspring 532. In some embodiments, the spring 532 is a linear compressionspring that is configured to exert a biasing force on the insert 504 topop or translate the insert 504 out of the cavity 508.

The body 502 includes an engagement member (e.g., a post, a pin, a malelocking member, an interface, etc.), shown as pin 520, that extendslongitudinally through cavity 508. In some embodiments, the pin 520extends only partially through cavity 508. The pin 520 can extend froman inner surface, a rear surface, an inner most face, etc., of the body502 at the distal end 530 of the body 502, shown as inner surface 518.The pin 520 can be fixedly coupled with the body 502 and includes an endportion configured selectively fixedly couple with a correspondingfemale portion of the insert 504 such that the pin 520 is configured toselectively fixedly couple with the insert 504.

Referring particularly to FIG. 4B, the insert 504 includes athrough-hole (e.g., an aperture, a bore, a blind-hole, an opening, acavity, a channel, a groove, etc.), shown as bore 526. The bore 526extends longitudinally through the insert 504 and is configured toreceive the pin 520 to facilitate selectively fixedly coupling theinsert 504 with body 502 (i.e., in a locked configuration). The insert504 includes an interlocking member (e.g., a locking member, aninterfacing member, a female member, etc.), shown as retainer 534. Theretainer 534 is configured to interface with, fixedly couple with,engage, etc., an end portion 522 of the pin 520 to fixedly couple thepin 520 and the body 502 with the insert 504 to secure the insert 504therein. The retainer 534 can be biased or driven into engagement withthe end portion 522 of the pin 520 by a spring. In some embodiments, theretainer 534 is configured to engage an annular groove (e.g., a recess,a notch, a depression, etc.) of the end portion 522 of the pin 520 toselectively fixedly couple the insert 504 with the body 502.

The insert 504 includes an interface (e.g., a button, a translatablemember, a slidable member, etc.), shown as button 524. When the insert504 is stored in the body 502 (e.g., as shown in FIGS. 4A and 4B), thebutton 524 faces outwards and can be pressed by a user to selectivelyde-couple or release the insert 504 from the body 502. The button 524 isconfigured to be received within a corresponding recess (e.g., innervolume, bore, etc.), shown as cavity 536. The button 524 can be slidablycoupled with the insert 504 and translate within the cavity 536. Whenthe button 524 is pressed or depressed by the user, the body 502 isselectably de-coupled from the insert 504 so that the insert 504 can bedrawn out of the cavity 508 of the body 502. A rear end of the button524 includes an angled surface 538 that is configured to engage acorrespondingly angled surface 540 of the retainer 534. Pressing ortranslating the button 524 into the cavity 536 drives the retainer 534to translate in a direction perpendicular to the translation of thebutton 524, thereby driving the retainer 534 out of engagement with theend portion 522 of the pin 520. Once the retainer 534 is translated ortransitioned out of engagement with the pin 520, the spring 532 drivesthe insert 504 to at least partially translate or pop out of the cavity508 of the body 502.

After being de-coupled from the body 502, the insert 504 can be drawnout of the cavity 508 by the user. The insert 504 is fixedly coupledwith a flexible member (e.g., a cable, a chain, a cord, etc.), shown asflexible member 542. In some embodiments, the flexible member 542 isfixedly coupled at a rear end 512 of the insert 504.

The flexible member 542 can be fixedly coupled with the insert 504within the aperture 544. The orientation of the insert 504 can bereversed and then re-inserted into the cavity 508 in an oppositedirection than the direction the insert 504 is drawn out of the cavity508. For example, the insert 504 can be re-inserted into the cavity 508with the front end 510 entering the cavity 508 first.

The insert 504 includes a locking aperture (e.g., a female lockingportion, an opening, a cavity, a bore, etc.), shown as the lockingaperture 546. In some embodiments, the locking aperture 546 extends adistance into the insert 504 through the front end 510. In someembodiments, the locking aperture 546 is an end of the bore 526. Whenthe insert 504 is re-inserted into the cavity 508 with the front end 510entering the cavity 508 first, the locking aperture 546 is configured toreceive the pin 520 and fixedly couple with the end portion of the pin520. In some embodiments, the pin 520 includes a tapered end such thatthe retainer 534 is driven to translate as the insert 504 is insertedinto the cavity 508. Once the insert 504 is inserted into the cavity 508a certain distance, the retainer 534 translates into engagement with theannular groove at the end portion 522 of the pin 520.

Referring particularly to FIGS. 4C and 4D, after the insert 504 isre-inserted into the cavity 508, the rear end 512 of the insert 504 isexposed and points outwards from the body 502.

The guide portion 804 can be acurved member that guides the flexible member 542 from within the frame12 of the bicycle 10 to the channel 810. In some embodiments, the guideportion 804 is reinforced with a structural member 820 that extends in adirection substantially perpendicular with the guide portion 804 betweenthe guide portion 804 and the body 802. In some embodiments, thestructural member 820 is a rib or a reinforcing member. The guideportion 804 and the structural member 820 can be integrally formed withbody 802. The guide portion 804 is configured to slidably interface withthe flexible member 542 and facilitates guiding the flexible member 542into the channel 810. The guide portion 804 can be a 90 degree elbow orarcuate portion.

The body 802 includes a recess (e.g., a groove, a channel, a slot,etc.), shown as groove 822, that extends along an outer face of the body802 at the front end 806 of the body 802. The channel 810 extends intothe groove 822. The groove 822 facilitates positioning the male lockingportion 824 of the flexible member 542 sub-flush or flush with theexterior face of the body 802.

The body 802 includes a cylinder (e.g., a lock, a locking device, alocking apparatus, a keylock, a locking cylinder, etc.), shown askeylock 848. In some embodiments, the keylock 848 is received within acorresponding opening (e.g., channel, groove, bore, aperture, etc.), ofthe body 802, shown as bore 850. The bore 850 extends longitudinallythrough the body 802. In some embodiments, the bore 850 extends onlypartially through an entire longitudinal length of the body 802 (e.g.,the bore 850 is a blind-hole). In other embodiments, the bore 850extends completely through the entire longitudinal length of the body802 (e.g., the bore 850 is a through-hole).

The keylock 848 is rotatably or pivotally and/or slidably coupled withthe body 802 within the bore 850. In some embodiments, an exteriorcylindrical surface of the keylock 848 slidably engages a correspondingcylindrical inner surface of the body 802 defined by the bore 850. Thekeylock 848 includes a keyhole 854 that is configured to receive anengage a key therewithin. In some embodiments, after the key is insertedinto the keyhole 854, the keylock 848 can be rotated or pivoted aboutits longitudinal axis.

The body 802 defines an aperture (e.g., a receiving aperture, a hole, ablind hole, a bore, etc.), shown as locking aperture 818. In someembodiments, the locking aperture 818 includes a female locking portionpositioned therein that is configured to engage and lock with (e.g.,selectably fixedly couple with) the male locking portion 824. In someembodiments, the locking aperture 818 has a shape that corresponds to anouter periphery of the male locking portion 824. For example, thelocking aperture 818 can have a circular-cross sectional shape that issized to receive male locking portion 824. By way of example, the lock800 may include an interlocking member that is the same as or similar tothe retainer 534. In some embodiments, rotation of the key that isinserted into the keyhole 854 transitions the female locking portionbetween an engaged or locked position/configuration and a disengaged orunlocked position/configuration. In some embodiments, rotation of thekeylock 848 (e.g., by rotating the key inserted into the keyhole 854)transitions the female locking portion between the engaged and thedisengaged positions. In some embodiments, rotation of the keylock 848translates or pivots the interlocking member to engage or disengage themale locking portion 824.

The flexible member 542 and the male locking portion 824 can be drawnout of the body 802, wrapped around an object, and inserted into thelocking aperture 818. In some embodiments, once the male locking portion824 is inserted into the locking aperture 818, the keylock 848 can betransitioned from the disengaged or unlocked configuration/position tothe engaged or locked configuration/position to fixedly couple the malelocking portion 824 with the body 802 (e.g., by rotating the key that isinserted into the keyhole 854). In this way, the flexible member 542 canextend or be extended from the body 802 of the lock 800, wrapped aroundan object, and locked to the body 802 at the locking aperture 818. Theoperation and use of the lock 800 is described in greater detail belowwith reference to FIG. 4S.

Referring particularly to FIGS. 4M-4P, any one of the lock 500, the lock600, the lock 700, or the lock 800 can be integrated into the frame 12of the bicycle 10. In some embodiments, the lock 500/600/700/800 isfixedly coupled with and/or integrated with the down tube 30 (as shownin FIGS. 4M-4P). In other embodiments, the lock 500/600/700/800 isfixedly coupled with and/or integrated with the top tube 90, the seattube 70, the head tube 20, etc. The lock 500/600/700/800 can extend intoan inner volume, shown as interior 34, of the down tube 30 (or otherportion of the frame 12). The lock 500/600/700/800 can be receivedwithin a correspondingly shaped and sized aperture or opening, shown asopening 36, of the down tube and is fixedly coupled with the down tube30. The lock 500/600/700/800 can be fixedly coupled with the down tube30 using a weld, fasteners, a frictional engagement, etc., or may beintegrally formed with the down tube 30.

Referring particularly to FIGS. 4Q-4S, the locking system 400 (e.g., anintegrated locking apparatus, an integrated locking system, etc.) can beused to selectively secure the bicycle 10 with an object 404. The object404 may be a stationary object that is adequately anchored (e.g., alight post, a fence post, a bicycle rack, etc.). The flexible member 542can be stored within and extendable from down tube 30. In someembodiments, the flexible member 542 is secured with the down tube 30 bya securing mechanism 402. In some embodiments, the securing mechanism402 is also a retraction mechanism such that the flexible member 542 isautomatically retracted into the down tube 30.

As shown in FIG. 4Q, the locking system 400 includes the lock 500. Thebody 502 of the lock 500 is fixedly coupled (e.g., fastened, welded,integrally formed, etc.) with the down tube 30 of the bicycle 10. Insome embodiments, the down tube 30 is a tubular frame member that hasthe interior 34 in which the flexible member 542 can be stored, and outof which the flexible member 542 can be extended or extracted. The body502 of the lock 500 can be positioned and fixedly coupled with the downtube 30 such that an exterior surface of the flange 516 is flush orsub-flush with an exterior surface of the down tube 30. For example, theflange 516 can be received within a recess, a groove, a depression, etc.in a wall of the down tube 30.

The insert 504 can be removed from the body 502 (e.g., selectivelyde-coupled from the body 502 by pressing the button 524) and extended orpulled from the down tube 30. As the insert 504 is extended from thedown tube 30, the flexible member 542 is extended from inside of thedown tube 30. The insert 504 and the flexible member 542 can then bewrapped around the object 404. The insert 504 can then be re-insertedinto the cavity 508 of the body 502 (e.g., in the configuration shown inFIGS. 4C and 4D) and locked with the body 502. Advantageously, thissecures the bicycle 10 with the object 404 and facilitates deterringtheft of the bicycle 10.

As shown in FIG. 4R, the locking system 400 includes the lock 600 or thelock 700. The body 602/702 of the lock 600/700 is fixedly coupled withthe down tube 30. In some embodiments, the body 602/702 is fixedlycoupled with the down tube 30 similarly or the same as the body 502 ofthe lock 500 is fixedly coupled with the down tube 30 (e.g., fixedlycoupled, fastened, welded, integrally formed, etc.).

The insert 604/704 can be removed from the body 602/702 and wrappedaround the object 404. In some embodiments, the insert 704 is firstrotated a predetermined angular amount so that the engagement protrusion790 can pass through the second aperture 784. The insert 604/704 canthen be secured with the flexible member 542. In some embodiments, theinsert 604/704 is transitioned into the disengaged or unlocked positionby inserting the key into the keyhole 654/754 and rotating the key.Rotating the key drives the keylock 648/748 to rotate, thereby drivingthe retainer 664/764 to translate and allowing the flexible member 542to be inserted into the inner locking volume 662/762. After the flexiblemember 542 is inserted into the inner locking volume 662/762 of theinsert 604/704, the user can rotate or pivot the key to transition thekeylock 648/748 and the retainer 664/764 into the locked or engagedconfiguration to secure the bicycle 10 with object 404. To release thebicycle 10 from the object 404, the key can be re-inserted into thekeylock 648/748, rotated in the opposite direction to allow the flexiblemember 542 to be released from the insert 604/704, and the flexiblemember 542 can be retracted into the down tube 30.

As shown in FIG. 4S, the locking system 400 includes the lock 800. Thebody 802 of the lock 800 is fixedly coupled with the down tube 30 of thebicycle 10. The flexible member 542 is extendable from the interior 34of the down tube 30 and can be drawn out of the down tube 30 through thebody 802. The flexible member 542 can be wrapped around the object 404and inserted into the locking aperture 818. The male locking portion 824can be inserted into the locking aperture 818 to secure and fixedlycouple the free end of the flexible member 542 with the body 802. Themale locking portion 824 can interlock within the locking aperture 818by simply being inserted into the locking aperture 818, or by beinginserted into the locking aperture 818 and then engaged by inserting akey into the keyhole 854 and rotating the keylock 848. The male lockingportion 824 can be disengaged or selectively de-coupled from the body802 by insertion and rotation of the key into the keyhole 854 in anopposite direction to disengage the male locking portion 824.

In some embodiments, the locking system 400 does not include the lock500, the lock 600, the lock 700, or the lock 800. In such embodiments,the locking system 400 may rather include a retaining element (e.g., abar, a U-bar, etc.) extending across the opening 36. Therefore, anindependent lock (e.g. a U-lock, a cable lock, etc.) can be loopedaround the retaining element to secure the bicycle 10 to the object 404.

Referring now to FIGS. 4T-4V, various embodiments of the securingmechanism 402 are shown. It should be understood that any combination ofthe securing mechanism 402 shown in FIGS. 4T-4V are within the scope ofthe present disclosure, and that the flexible member 542 can be securedwith the down tube 30 or automatically retracted into the down tube 30by the securing mechanism 402. Further, any of the embodiments of thesecuring mechanism 402 shown in FIGS. 4T-4V and described in detail withreference to FIGS. 4T-4V can be used with any of the lock 500, the lock600, the lock 700, or the lock 800.

Referring particularly to FIG. 4T, the securing mechanism 402 includes alinear biasing element, shown spring 406, that is anchored to or fixedlycoupled with an end of the flexible member 542. In some embodiments, thespring 406 is fixedly coupled with the down tube 30. The spring 406 canbe positioned within the interior 34 of the down tube 30. The spring 406can be extended a predetermined length to facilitate extension of theflexible member 542. As the flexible member 542 is drawn out of the downtube 30, the spring 406 exerts a recoil force or a return force to theflexible member 542 to draw the flexible member 542 back into the downtube Advantageously, the spring 406 facilitates an automatic retractionof the flexible member 542 into the down tube 30.

Referring particularly to FIG. 4U, the securing mechanism 402 includes aretraction mechanism, shown as torsional spring 408. The torsionalspring 408 is configured to retract the flexible member 542 into thedown tube 30. Drawing or pulling the flexible member 542 out of the downtube 30 may load the torsional spring 408 such that when the flexiblemember 542 is released, the torsional spring 408 draws the flexiblemember 542 into the down tube 30. The flexible member 542 can be woundonto a spool and stored within the down tube 30 until it is extendedfrom the down tube 30 for securing the bicycle 10. The torsional spring408 can drive the spool to wind the flexible member 542 onto the spool.The spool can be pivotally coupled within the interior 34 of the downtube 30.

Referring particularly to FIG. 4V, the down tube 30 includes an orificeplate, structural members, laterally extending members, etc., shown asengagement members 414.
